I have been asked in an interview how one can return more than one value from function. I have answered saying by using pointers we can achieve(call by reference) this in C. Then he told me he is looking for some other way of returning more than one value. I said we can return a struct object but here also he didn't seem to be impressed.

推荐答案

最棘手的问题是，面试官有一些解决方案，他们特别高兴，在思想和他们是你是否有同样的巧妙伎俩他们可能分级您还是不行。

The tricky problem is that the interviewer has some solution they are particularly happy with in mind and they are likely grading you by whether you have the same clever trick as them or not.

您可能只是仅举几方面，如你做，但仍不能落在他们的秘招。如果你知道自己的密招，你很可能不能与它pssed IM $ P $。

You could just name a few ways such as you did, and still not fall upon their secret trick. And if you knew their secret trick, you could well not be impressed with it.

因此​​，在这些情况下，其将其从采访到谈话。一旦你发现你没有对他们的自我感动，你能避免对航向恐吓我不知道，我放弃，而是尝试一下，让你有什么聪明的解决方案？是否有一个IN-房子配方在此XYZ公司？等等。

So in these situations, its to turn it from interview into conversation. Once you detect you're not moving towards their ego, you can avoid heading towards the intimidating "I don't know" "I give up" and instead try out the "so do you have any clever solution? Is there an in-house recipe for this at Xyz Inc?" etc.

在其明显的自我IM pressed溶液中的任何一瞥，你又回到坚固的地面上，你可以谈论它，并问他们是否有想过浮现在脑海中，基本上采访他们的各种因素。

Any glimpse at their obviously self-impressed solution and you are back on firm ground where you can talk about it and ask them if they have thought about various factors that come to mind and basically interview them.

每个人都喜欢一个很好的倾听者，并让他们谈论他们的招数是让他们离开采访throughly IM $ P $与你pssed的好方法！ ;）

Everyone loves a good listener, and getting them to talk about their tricks is a good way to get them to leave the interview throughly impressed with you! ;)
